The Postal Museum and Mail Rail

Ride the tiny underground railway that carried London’s post for 75 years.

The Mail Rail ride is fifteen minutes in a miniature train through the old tunnels under Mount Pleasant, and children love it. The museum upstairs is compact and well done. Entirely indoors, so a good rainy-day pick; book the ride in advance because slots go.

When it works

Indoors, so the weather does not matter. Best morning, afternoon.

Good for kids and step-free visits.
